4.1 General Description
PJ500C-LCD, PJ700C-LCD e PJ1000light are compact radio broadcasting
amplifier manufactured by R.V.R. Elettronica SpA featuring adjustable RF power
output up to 500, 700 and 1000 W, respectively, under 50 Ohm standard load and
less than 20W drive power requirement.
PJ500C-LCD, PJ700C-LCD and PJ1000light have been designed for installation
in a 19”x3HE box for rack.
These amplifiers incorporates a low-pass filter to keep harmonics below the limits
provided for by international standards (CCIR, FCC or ETSI).
Two major features of PJ500C-LCD, PJ700C-LCD and PJ1000light are compact
design and user-friendliness. Another key feature is its modular-concept design:
the different functions are performed by modules with most connections achieved
through male and female connectors or through flat cables terminated by
connectors. This design facilitates maintenance and module replacement.
The RF power section of PJ500C-LCD uses two MOSFET modules delivering up
to 300W output power each, PJ700C-LCD uses two MOSFET modules delivering
up to 350W output power each, whereas PJ1000light features three MOSFET
modules with up to 350 W output power each.
An LCD on the front panel and a push-button panel provide for user interfacing with
the microprocessor control system, which implements the following features:
• Output power setup
• Power output enable/disable
• User-selectable threshold settings for output power alarm (Power Good
feature)
• Measurement and display of amplifier operating parameters
• Communication with external devices, as programming systems or telemetry
systems through RS232 or I2C serial interface

5. Quick guide for installation and use
This section provides a step-by-step description of the machine installation and
configuration procedure. Follow these procedures closely upon first power-on
and each time any change is made to general configuration, such as when a new
transmission station is added or the exciter is replaced.
Once the desired configuration has been set up, no more settings are required
for normal operation; at each power-up (even after an accidental shutdown),
the amplifier defaults to the parameters set during the initial configuration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and firmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When configuring and testing the transmitter in which the amplifier
is integrated, be sure to have the Final Test Table supplied with the machine ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
5.1 Preparation
5.1.1 Preliminary checks
Unpack the amplifier and immediately inspect it for transport damage. Ensure that
all connectors are in perfect condition.
Provide for the following (applicable to operating tests and putting into service):
√ Single-phase 230 VAC or 115 VAC (-15% / +10%) mains power supply with
adequate ground connection
√ FM exciter with adjustable output power up to 20W (as a minimum), like RVR
Elettronica PTX30-LCD
√ For operating tests only: dummy load with 50 Ohm impedance and adequate
capacity (500w for PJ500C-LCD, 700w for PJ700C-LCD or 1000 W for
PJ1000light as a minimum)
√ Connection cable kit including:
• Mains power cable

Mains power supply
WARNING: Disconnect mains power supply before beginning these
procedures.
Both power supply units (please see chapter 8.1 for a detailed description) are
equipped with fuses and voltage selection blocks: check all fuses and voltage
selection blocks to ensure they are properly rated for the power mains and
change them as required to match mains voltage.
All mains power supply protection fuses are conveniently located on the rear panel
and are easily accessed (see figure 6.2): to check or replace a fuse, disconnect
machine from power mains, unscrew fuse cover and pull fuse out of socket.
The following fuses are used:

Table 5.1: Fuses
Ensure that machine is appropriately set for available mains voltage (supply voltage
rating is reported in the Final Test Table) as follows: disconnect machine from
mains and ensure that the voltage selection block of the power supply located on
the rear panel (see fig. 6.2) is set to the appropriate voltage; change setting as
required.
The main power supply unit is the full-range type and requires no voltage setup.
When supply voltage is other than 230 Vac and might cause erratic operation (say,
less than 200 Vac), it may help to move jumper JP3 on the PFC controller board
from position 2-3 to 1-2 (see PFCPSL1000 diagram, in figure 9.1 and detail in
figure 5.1 below).

5.1.3 Connections
Connect the output of a suitable FM exciter (for instance, PTX30-LCD exciter
available from R.V.R. Elettronica) to the RF input (see figure 6.2) using a 50-Ohm
coaxial cable with suitable connectors. To begin with, set exciter to minimum output
power and switch if off.
Connect the amplifier INTERLOCK OUT output (figure 6.2) to the matching
INTERLOCK IN input fitted on all R.V.R. Elettronica exciters as standard; if your
exciter is a different brand, identify an equivalent input.
Connect the RF output (see figure 6.2) to an adequately rated dummy load or to
the antenna.
WARNING: Electric shock hazard. Never handle the RF output connector
when the machine is powered on and no load is connected. Injury or death
may result.
Ensure that the POWER switch on the front panel (see figure 6.1) is set to
“OFF”.
Connect the mains power cable to the MAINS terminal board on the rear panel
(see figure 6.2).
Note : The mains must be equipped with adequate ground connection properly
connected to the machine. This is a pre-requisite for ensuring operator safety and
correct operation.
WARNING: The power supply connector is a terminal board. Ensure the wire
is not live before performing the connection.
Please see figure 5.2 for a hook-up diagram showing RF connection between
amplifier and exciter and load connection.

5.2.3 Power check
Ensure that the ON light turns on (see figure 6.1). Machine name should appear
briefly on the display, quickly followed by forward and reflected power readings
(figure 5.2 - menu 1). If RF output is disabled, these readings will be zero.
5.2.4 How to enable Local mode and RF output
Check current mode setting and enable Local mode (if not already enabled)
following menu path Fnc ⇒ Loc ⇒ Local (figure 5.2 - menu 4): if left disabled,
the machine will not accept the next commands.
Check current RF output setting and enable output (if not already enabled) following
menu path Fnc ⇒ Pwr ⇒ ON (figure 5.2 - menu 4)
Check output power level and set to maximum level (if not already set to maximum)
from the Power Setup Menu, which you can call up by pressing these keys in the
order: ESC (opens Default Menu) ⇒ ENTER (hold down for 2 seconds) ⇒ SET
⇒ use key to set bar to maximum limit (figure 5.2 - menu 2).
5.2.5 Input power check and setup
Go to Pwr menu (figure 5.2 - menu 5) and look up forward output power Fwd,
reflected power Rfl and input power Inp readings.
With drive power set as specified in the Final Test Table, amplifier output power
should be 500W (for model PJ500C-LCD), 700W (for model PJ700C-LCD) or
1000W (for model PJ1000-light) or higher: if needed, fine tune drive power until
achieving rated output power. Never exceed 550W (for model PJ500C-LCD), 770W
(for model PJ700C-LCD) or 1100W (for model PJ1000-light) output power.
Note : Normally, drive power should not exceed 20W (typically 18W): higher drive
power requirements are a symptom of abnormal operation.
WARNING: Drive power levels above 20W (typically 25W), result in exceeding
input power, which causes a temporary amplifier lock-out (see section 5.3.4.1
- Alarms and Faults for more details).
5.2.6 RF output power level control
IMPORTANT: The amplifier incorporates Automatic Gain Control and output
power is modulated based on the power level set by the user and actual operating
conditions, such as temperature, reflected power and other parameters. Drive
power must be kept steady at maximum output power capacity. Please read section

WARNING:Equipment is capable of delivering more than rated output power
(500W for PJ500C-LCD, 700W for PJ700C-LCD or 1000 W for PJ1000-LIGHT);
however, never exceed the specified power rating.
NOTE: Exciter drive power setting should never exceed 20W, or it will trigger an
Overdrive Alarm.
NOTE: If power is set to 0 W in the edit mode, the INTERLOCK OUT contact
(chap. 6.2) trips and external exciter power is immediately inhibited.
Next, you can review all operating parameters of the machine through the
management firmware.
Normally, the machine can run unattended. Any alarm condition is handled
automatically by the safety system or is signalled by the LED indicators on the
panel or by display messages.

User Manual
PJ500C-LCD, PJ700C-LCD & PJ1000light
PgD
Modifies Power Good threshold for forward power. The Power Good
rate is a percent of equipment rated power (500W for PJ500C-LCD,
700W for PJ700C-LCD and 1000 W for PJ1000-LIGHT), not of forward
output power. This means that this threshold set at 50% will give 250,
350 and 500 W, respectively, regardless of set power level. The Power
Good feature enables output power control and reporting. When output
power drops below set Power Good threshold, the equipment changes
the state of pin [7] of the DB15 “Remote” connector located on the rear
panel (figure 6.2).

too high.
Alarm monitoring cycle is as follows: when an alarm condition is detected, alarm
counter increases by 1 unit, machine goes into lock-out state and the display shows
the cause for the stop (chap. 5.3.4.1). After 15 seconds, the machine attempts
to re-start; if a new alarm condition is detected, cycle is repeated over and over
again up to 10 times maximum.
If machine re-starts successfully, all alarm counters are reset after 30 minutes’
regular operation. After 10 alarm conditions triggered by the same cause, the
machine goes into fault lock-out mode, a lock-out mode warning appears on the
display and the “FAULT/LOCK” LED turns on (chap. 6.1).

PJ500C-LCD, PJ700C-LCD and PJ1000light power supply section is made up
of a surge protection module and two power supply units:
24 / 32
Rev. 1.0 - 20/06/08
User Manual
PJ500C-LCD, PJ700C-LCD & PJ1000light
1. Surge Protection module (see description in chap. 8.1.1): protects the
machine from possible voltage surge events and electric discharges in the
power mains.
2. Power amplifier supply unit: provides adequate power supply for RF power
amplifier modules. It is a switching power supply unit with PFC full range; for
details of the PFC and converter modules, please see chapters 8.1.2 and 8.1.3,
respectively.
3. Service power supply unit: provides adequate power supply for all modules
except RF power modules. Major components of this 50-Hz transformer-based
power supply unit are:
-
Power switch
-
Service fuse
-
Mains voltage selector
-
Service transformer
NOTE: Please see chapter 5.1 for power supply unit settings.
8.1.1 Mains power supply pulse protection (SLSRGPRPJ1KM)
This module is enclosed in a sealed metal case (see figure 9.1); it features two
externally mounted mains fuses (figure 6.2) and accommodates a bank of surge
arresters that protect the machine from any surge events in the power mains.
Mains voltage is brought from this module to the main Power switch on the front
panel (figure 6.1), which relays it to the service transformer TR1 (figure 9.2).
Inside the surge protection module, a suitable 24VDC relay controlled via the
interface board isolates (single line) mains voltage to be fed to the power amplifier
power supply unit (PFC module). This way, mains power supply to PFC is enabled
when these requirements are met:
• POWER switch on front panel (figure 6.1) set to ON;

8.1.3 Switching power supply (PSL2403-03 and PSL5034)
The switching power supply incorporated in this amplifier feeds 50 VDC to the RF
power modules with 25 A maximum current for PJ500C-LCD and PJ700C-LCD
and 34 A maximum for PJ1000light.
This module has a control input that enables output voltage reduction when needed
(for instance, in the event of RF output power reduction). Another input signal is
used to shut down the power supply (0V output voltage) when any one of the
following conditions is verified:
• Power output disabled (set to OFF) by user in FNC operation menu (menu 4,
see chapter 5.3.1);
• Regulated power set to 0 Watt using the edit mode (menu 2, see chapter
5.2);
• An alarm or fault condition has occurred (see chapter 5.3.4).
8.2 Interface board (SL010IN5001)
This board performs the following tasks:
• It uses AC voltage from transformer TR1 to generate and distribute service
power supply over the panel board;
• It controls and provides interfacing of the mains surge protection module
(SLSRGPRPJ1KM);
• It controls and provides interfacing of the power amplifier power supply module
(PSL2403-03 and PSL5034);
• It processes and provides interfacing of the control signals to/from the Bias
Board (SLBIAS1K3U-2);
• It processes and provides interfacing of the control signals to/from the Panel
Board (SL007PC2003);
• It acquires and processes the input signals from the input power measurement
board (SLMPIPPJ1KC);
• It feeds and operates the cooling fans;
• It feeds and controls the LED indicator board.
8.3 Panel board - CPU (SL007PC2003)
The panel board accommodates the microcontroller that runs the machine control
software and all user interface elements (display, LED’s, keys, …).

PJ500C-LCD, PJ700C-LCD & PJ1000light
This board is interfaced with other machine modules via flat cables and provides
for power supply, control signals and measurement distribution.
8.4 PWR Input Measure Board (SLMPIPPJ1KC)
This board enables measurement of the following parameters:
• Input power measurement;
• Main heat sink temperature measurement by an LM 50 sensor mounted on the
board; it obtain the temperature through a fixing screw.
Both measurements are adequately processed and sent to the interface board
that controls the protection modules and relays the signals to the CPU board to
enable readings to be displayed.
8.5 Power amplifier
The RF power amplification section consists in several power modules (two on
the PJ500C-LCD and PJ700C-LCD, three on the PJ1000light) coupled through
a Wilkinson splitter and combiner using strip-line technology.
Each RF module of the PJ500C-LCD (code SL010RF1002) provides 300 W rated
power - which rise up to 350 W each for the PJ700C-LCD and PJ1000light RF
modules (code SL010RF2002) - using a single active element built using MOS
technology. RF modules are fed by the switching power supply via the Bias
board.
The splitter (Splitter Board code SLSITEX500L1 for PJ500C-LCD and PJ700CLCD, or SLSPLTEX1KL1 for PJ1000light) splits the incoming power input signal
equally to all RF modules. The combiner (Combiner Board code SLCOTEX500L1
for PJ500C-LCD and PJ700C-LCD, or code SLCMBTEX1KL1 for PJ1000light)
combines the power output signals available at module outputs to obtain total
amplifier power.
Splitter, amplifiers and combiner have been designed to sum amplifier output power
signals in phase, so as to keep unbalance and power dissipation to a minimum.
The whole RF section is mounted on a finned heat sink with fan cooling.
8.6 LPF Board (SLLPFTEX1KL)
This board incorporates a low-pass filter to keep amplifier harmonics within
permissible limits as specified by international standards.

27 / 32
PJ500C-LCD, PJ700C-LCD & PJ1000light
A directional coupler is provided at filter output to measure forward and reflected
RF output power; power readings are relayed to the Interface and Bias boards to
enable processing and display.
The LPF board incorporates an RF output (having a level about -60 dB lower than
output level) which is brought to a BNC connector (figure 6.2). This provides a
convenient test point to check carrier characteristics, but does not ensure an
accurate assessment of higher harmonics.
8.7 BIAS board (SLBIAS1K3U-2)
The main purpose of this board is to control and correct the bias voltage of the RF
amplification section MOSFETs.
It also provides a measure of the total current absorbed by the RF modules and
incorporates a dedicated circuit for power supply fault reporting.
Under normal conditions, bias voltage is adjusted according to set output power
using feedback based on actual output power reading (AGC).
Abnormal conditions affecting bias voltage so as to trigger foldback current limiting
are:
- Exceeding reflected power at output
- External AGC signals (Ext. AGC FWD, Ext. AGC RFL)
- Temperature too high
- Any one RF module drawing too much current.
8.8 External Telemetry Interface Board (SLTLMTXLCD03)
This board provides an I/O interface for the CPU with the outside environment.
All available machine input and output signals are brought to the REMOTE DB15
connector (chap. 6.3.4).
Also mounted on this board is the INTERLOCK IN BNC connector (figure 6.2)
which can disable device power output. When the central pin is closed to ground,
output power is limited to zero until ground connection is removed.
The INTERLOCK OUT BNC connector (figure 6.2), when used in combination
with an R.V.R. amplifier, is connected to the exciter REMOTE or INTERLOCK IN
connectors using a BNC-BNC connector. In the event of an amplifier fault, the
central conductor is connected to ground and the transmitter is placed into forced
standby mode.
